First, Better Amphetamin, oclockvita, and RinCheat don't overclock the system. It only takes the clock speeds up to 100% of Sony's approved SoC. Oclockvita is better than Better Amphetamin, as it has a two FPS advantage over Better Amphetamin. I don't use RinCheat, but since that's a multi-tool plugin, that has been updated more recently, but that doesn't necessarily mean that RinCheat has better support in that area
